Appneaaomea my 24, 1922. serial N10. 563,187.

To all whom t may concern:

Be it known that I, BENNo B. LEUSTIG,

a citizen of the ,United States, and resident of Cleveland, in the county of Cuyahoga and State ofvOllio, have invented a certain 'new and useful Y Improvement in Spring Covers, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawines, forming a part of'this specification.

spring covers, and is particularly concerned with the provision of a. novel type of metal spring cover to be used on the laminated springs of automobiles and other vehicles.

The objects of my invention are: f. First: To provide a flexible cover -for the laminated springs of automobiles and other vehicles, which will elfectually exclude dirt, dust and Water from the springs, and at the same time embody means for insuring the proper lubrication of the springs;

, Second :l To provide a cover of the character described, which, within certain limitations, i's adjustable to springsof diiferent lengths; 1 Third: To provide a spring cover which is made entirely of metal, but which at the modate itself to lthe movements of -the springs;

Fourth: To provide a metal springbover comprising two channel shaped members, one of whi-ch is inverted relatively to the other, the flangesof the two channels lbeing' positioned in overlapping, relation and notched to provide'the necessary flexibility,

\ the notches forming a pluralityof longitudinally spaced tongues, the tongues of one channel being positioned to cover the notches in the other channel;

Fifth: To provide a spring cover of the character described, in which means are provided lfor connecting the outer ends of oppositely disposed tongues on the outer channel so as to form apluralityofindependently movable sections: g* v Sixth: To provide acover. of the type described comprising means for rigidly securing the ltwo channel shaped members together. and at the same time protecting the channel shaped member which is engaged /Iy invention relates to improvements in 1 by the ends of the spring laminations against injury upon the rebound of the spring, thc same meansacting as a snubber;

Seventh: To provide novel and improved means of supplying lubricant under pressure lto the spring, and

Finally: To provide means for sealing the rcover to the spring so as to prevent the escape of lubricant therefromi The abo-ve and other objects will be apparent as this description progresses, reference being had to the accompanying drawings, in which- Figure l is a side elevation of a quarter elliptical spring provided with one of my metal covers;

Figure 2 is a central longitudinal section through a portion of the spring cover as applied to a spring;

Figure 3 is a fragmentary bottom-view;

Figure 4 is a transverse section taken on line 4--4 of Figure 2;

Figure 5 isa similar view taken on line 5-5 of Figurey 1, and

illustrating the manner in which the 'various parts kare assembled relatively to each other.

`Throughout the several views, similar refference c aracters will be used for referring to similar parts. In Figure 1,"1 have illustrated the forward end 10 of a side channel of an automobile chassis, to which is secured the spring 11 which is lsupported from axle 12, these two members beingl secured together by a well known means, the particular construction of which is not essential to my invention. The upper lamination, or leaf, 13, of the spring is provided at its outer end with an eye 13 for receiving the lshackle bolt 14 which secures it to the free end ofthe channel bar 10. The construction just described, as Well as the construction` of the spring itself, which comprises a plurality of spring leaves or laminations, is well known, and further reference thereto is unnecessary.

My improved spring cover comprises two pairs of nested channel shaped members. The inner pair of channel shaped members comprises the channel shaped members 15 and'l A(see Figure 4), and the outer pair of channel shaped members comprises the channel shapedA members 17 and 18. rl`he last mentioned channel shaped members are inverted relatively to the first pair, and the flanges 19 and 20 of these inverted channel shaped members enclose the flanges 21 and 22 of the first mentioned pair, as shown in Figure 4. Notches 23, cut through the flanges 21 of the channel shaped member 15, form a plurality of longitudinally spaced tongues 24, and at the same time render this channel shaped member flexible so that it can fieX in a p-lane parallel with its flanges. Similar notches 25, 26 and 27, cut through the flanges 19, 20 and 22 of the channel shaped members 18, 17 and 16, render these channel shaped members flexible in planes parallel with their flanges,'and at the same time form the @longitudinally spaced tongues 28, 29 and 30 on the channel shaped members 18, .17 and 16.

When the channel shaped members are assembled upon the spring, as shown in the various figures, 1 to 5 inclusive, the tongues 30 cover the notches 23 between the tongues 24; the' tongues 29 cover the notches 27 between the tongues 30; and the tongues 28 cover the notches 26 between the tongues 29, so as to provide a longitudinally flexible but liquid-tight casing for enclosing the spring.

For securing the two pairs of channel shaped members together, 1 provide the free ends of each of the tongues 28 of the channel shaped member 18 with a struck out portion forming a loop 31, and then pro` vide a clip 32 which is made from a stri of sheet metal having the `11p-,turned endsi 33, which can be inserted through the loops 31 of a pair of oppositely disposed tongues and then turned outwardly over these loops, as shown at 34 in Figure 4. ,f

For the purpose of reinforcing the bot-` tom of the chann'el shaped\ member 15 against theV thrusts of. the ends of the spring leaves during rebound of the spring, and at the same time to limit, as much as possible, this rebound, 1 lprovide they longitudinally extending metal strip 35, which may, if desired.r be secured to the bottom of the channel shaped member 15 by means of a rivet or rivets 36. This strip is made sufhciently thickto enable it to withstand the thrusts of the ends of the sprirlg leaves. u

At the end of the spring cover, adjacent the eye 13', 1 provide the `two channel shaped members'y40 and 41, the flanges 42 and 43 of which overlap, as shown in Figc ures 1 and 5. rll`he anges 42 are` each provided with a Apair of spaced tongues 45 which project through slots 46 formed in the corners of the channel shaped member 41, and are bent outwardly and downwardly alongside the anges of the channel sha member 41, as shown in Figures 1 md5,

retener to securel these two channel shaped members together on the outer end of' the cover.

The two channel shaped members 41 andy 42 can'be shifted longitudinally of the remaining portion of the cover to adjust the l cover to springs varying slightly in length. The inner ends of the'two pairs of channel shaped members are secured to the spring by means of the cross bars 47 and the bolts 48.

For the purpose of sealing the cover upon the springso as to prevent the escape of lubricant therefrom7 l prefer to insert short.

pieces of felt/49 between the top and bottom sides of the spring leaf 13 and the adjacent channel shaped members, as shown in Figures 2 and 5, and to hold these pieces of felt in place, 1 form extensions 50 on the flanges 42 of the channel shaped member 40,-a`nd extensions 51 and 52 on the channel shaped member 41, which can be bent inwardly around the outsides of the felt strips 49 to hold them in place against the pressure of the lubricant. 'il also provide the bottom of the charinel shaped member 40 with an extension 53 which can be bent around the eye 13 of the upper leaf of the spring to anchorthe channel shaped members 41 and `42.

For the purpose of supplying lubricant to the spring, 1 form a nipple 55 ,on the strip 35, to whichlis secured the inner end Lof the lubricant conducting member 55',

which is here illustrated as being one of the fittings forming a part of a well known system of lubrication, this fitting being provided with a spring pressed closure 56, and a pin 57 projecting from the side thereof, for making a detachable connection with a lubricant compressor, capable of forcing lubricant into the casing or cover under high pressure. 'llhe particular construction of the lubricant conducting member 55' forms no part of my resent invention as long as it is capable or introducing lubricant into the interior of the cover.

The bottoms of the channel shaped members 15 and 16 are provided with suitable i'io openings 58 through which .the lubricant Fi re 2. A

lllhilel have described the details of construction of the preferred embodiment of my invention, it is to be clearl understood that my rnvention is not limite to these details, but is capable of other adaptations and modifications within the scope of the ap ended claims.
